Facts about ammonia
In Dutch sewage water treatment plants tens of thousands of tons of ammonia-nitrogen are destructed to nitrogen gas every year at the cost of 9 to 40 MJ/kg NH4-N (Annamox and conventional nitrification/denitrification respectively).
At the same time in fertilizer plants an even bigger amount of nitrogen gas is converted to ammonia in the Haber-Bosch process also at the cost of 45 MJ/kg NH4-N.
Power-to-Protein is about closing this artificial nitrogen cycle by direct N upcycling as microbial protein.
The basis is a highly efficient microbial resynthesis process with a mixed culture of bacteria that use hydrogen as an energy source.
Idea holder and emeritus professor at Ghent University (LabMET), prof. dr. ir. Willy Verstraete states:
“The technology for recovery of reactive nitrogen as microbial protein is available but a change of mindset needs to be achieved to make such recovery acceptable.”
Together with its research partners KWR Watercycle research Institute investigates the technological, economic and environmental feasibility of the Power-to-Protein concept.
News and Updates
This summer Avecom and KWR will start the construction of the pilot plant for the production of SCP on-site. Recently the functional design was completed including the P&ID and subsequently a HAZOP was performed. The first pilot location will be at the WWTP Enschede of Water Board Vechtstromen.
Collaboration Agreement for the Power-to-Protein project phase 2 as part of the TKI-Water Technology programme is signed by all partners.
December 2015: Power-to-Protein is presented in “De Ingenieur” as one of the possible breakthroughs in 2016: “The best of 2016”.
